My anecdotal experience (partially informed by working on the Windows Wi-Fi team) is that iOS/macOS are more aggressive about switching APs. It's a tradeoff - on one hand, you can have disruptive scans like this, but on the other, if it results in switching to a better network during a long period when the user is stationary, it can result in a better experience.

It also depends a lot on what your hardware is, whether you're doing a full scan or a partial scan, whether you have more than one NIC etc, etc.

"better experience" only if you aren't doing something latency-sensitive, like a video call.

Video calls aren't hyper latency sensitive, there is already a lot of latency in encoding and processing effects. I'd imagine this could be most disruptive to video games but this isn't a market Apple has done much to work with.
